Hook Development

To create Claude Code hooks, you design structured hook configurations for events like PreToolUse or SessionStart, wire them into hooks.json, and organize reusable logic under scripts/ to enable event-driven automation, safety checks, and context loading.

Prompt-based hooks are configurations that reason over inputs and outcomes to enforce policy, validate actions, and load context within Claude Code plugin workflows. You need them when deterministic command checks are insufficient for contextual decision-making.

Yes, Claude Code hook development requires no special platform beyond standard CLI tooling. You need bash and jq installed to parse event payloads and execute the scripts that power your automated plugin workflows.

The best way to enforce safety checks is by combining prompt-based PreToolUse hooks for contextual validation with optional command hooks for deterministic checks, wiring both into your hooks.json file for comprehensive policy enforcement.

You structure references and scripts by placing reusable bash logic under scripts/ and implementation guidance under references/. This organization accelerates hook iteration, maintains structured patterns, and enables safer deployments across your plugins.
